This change adds code that detects if an expression can definitively never be constant. We use this to analyze the initializer expressions in const constructors. This check is not entirely water tight, but together with the checks in canonicalization code catches most illegal initializer expressions. The const constructor of class Symbol turns out to be illegal. The name verification check can't be part of the constructor code.
